Audi Electrical Wiring Manual: A6 Sedan 1998-2000, A6 Avant 1999-2000, allroad quattro 2000

POINTS TO REMEMBER:

1. When making wiring harness repairs, use only the tools and components from the VAS 1978 Wiring Harness Repair Kit.



2. Replace any harness that cannot be repaired and restored to its original configuration using the VAS 1978 kit.



3. When making repairs by splicing a new length of wire, choose a replacement wire that is the same size as the original, or greater.



4. Choose from among the color-coded connector terminals and other kit components to match them to the proper wire size.



5. If it is necessary to join an original wire and a replacement wire using a butt-joint crimp connector, the wires and the crimp connector must be matched in size to ensure a reliable crimp.



6. Check for special surface treatment on connector terminals. If, for example, the original terminal was gold-plated, a gold-plated replacement must be used.



7. If heat-resistant wire was used in the original harness (typically with a softer, matte-finish insulation), the equivalent wire must also be used for the repair.



8. Always replace single-wire seals, where applicable, using color-coded seals that match the wire size. Refer to the VAS 1978 Instruction Manual.



9. Secondary locking features are critical components that help maintain positive terminal contact. Always fully insert the terminal in the housing before engaging the lock.



10. Always inspect all features of the connectors and terminal housings for damage before reassembly.
